Abstract
The utility model discloses a heat dissipation device for a cabinet body and belongs to the technical field of heat dissipation. The heat dissipation device for the cabinet body comprises a draught fan and a controller which controls power supply connected with the draught fan. The heat dissipation device for the cabinet body is characterized in that an air speed sensor which can transmit electric signals to the controller is arranged in an air channel of the draught fan. Due to the fact that the air speed sensor is arranged in the air channel of the draught fan, the air speed sensor transmits the electric signals to the controller and enables the controller to detect a real working condition of the draught fan through the air speed sensor, and therefore the problem that equipment continues working to be damaged after a draught fan is damaged in the prior art is solved.
Description
Technical field
The utility model belongs to the heat dissipation technology field, is specifically related to a kind of cabinet and uses heat abstractor.
Background technology
Current, the heat abstractor major part that is applied to cabinet is provided with blower fan and controller, and controller can turn on and off the power supply of blower fan automatically according to the ruuning situation of cabinet inner electronic equipment, and detects the on off state of auxiliary contact in the blower fan distribution device in real time.In practical application; This kind heat abstractor only can be judged whether operate as normal of cooling system through the state of auxiliary contact in the blower fan distribution device; Under the situation that blower fan breaks down, controller is can't be detected, and at this moment electronic equipment continues operation; And blower fan can't in time be discharged the heat that electronic equipment discharges, and causes electrons equipment takes place overheated and damages.
The utility model content
The utility model technical problem to be solved provides a kind of cabinet and uses heat abstractor, can react the operating state of blower fan truly.
For solving the problems of the technologies described above; The technical scheme of the utility model is: design a kind of cabinet and use heat abstractor; Comprise blower fan and controller; Controller control connects the power supply of blower fan, it is characterized in that: in the air channel of blower fan, air velocity transducer is set, air velocity transducer is given controller with electrical signal transfer.
Preferably, also comprise first or/and second temperature sensor, first or/and second temperature sensor electrically connects controller.
Compared with prior art, the beneficial effect of the utility model is:
1, owing in the air channel of blower fan, air velocity transducer is set; Air velocity transducer is given controller with electrical signal transfer; Make controller can detect the real work state of blower fan through air velocity transducer, avoided after blower fan damages in the prior art, equipment still continues to move and the drawback of damaging.
2, owing to also be provided with first or/and second temperature sensor; Controller can be according to first or/and the numerical value of second temperature sensor be closed blower fan automatically; Make the control of blower fan science more; The temperature that cabinet that understanding is monitored that simultaneously can be real-time is interior is convenient to that controller detects in real time, logic determines, and handles it.

Fig. 2 is the logic control block diagram of controller.
Mark among the figure: 1, controller; 2, second temperature sensor; 3, cabinet; 4, electronic equipment; 5, air velocity transducer; 6, first temperature sensor; 7, blower fan.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
As shown in Figure 1; The utility model is provided with controller 1, blower fan 7, air velocity transducer 5, first temperature sensor 6 and second temperature sensor 2; Controller 1 control connects the power supply of blower fan 7; Air velocity transducer 5 converts wind speed to electrical signal transfer and gives controller 1, and first, second temperature sensor 6,2 becomes electrical signal transfer to give controller 1 temperature transition.Wherein, Blower fan 7 is installed on cabinet 3 tops or rear portion; Be used for outside cabinet 3, forcing exhausting, what in the air channel, form distinguished and admirablely takes away the heat that cabinet 3 inner electronic equipments 4 are produced, according to the difference of installation site, wind direction; Can be centrifugal blower or axial flow blower, its power be by caloric value, the air quantity decision of electronic equipment 4.
First temperature sensor 6 is installed in the air channel end, is used for detecting the heat radiation airflow temperature, and second temperature sensor 2 is installed in electronic equipment 4 surfaces, is used for the temperature of detected electrons equipment 4.Used first, second temperature sensor 6,2 can be a thermal resistance, any one in the conventional sensors such as thermocouple.
As shown in Figure 2; During use, above-mentioned controller 1 powers on and initialization, the operating state of beginning detected electrons equipment 4; When the electronic equipment in the cabinet 34 is started working; Controller 1 can receive a digital quantity signal, although this moment, temperature did not rise, controller 1 is controlled blower fan 7 immediately and started working.When electronic equipment 4 work stopped, blower fan 7 continued heat radiation, and when the temperature value of first, second temperature sensor 6,2 was reduced to lower limit set value, controller 1 cut out the power supply of blower fan 7.In the process of blower fan 7 work, when the temperature value of first temperature sensor 6 or second temperature sensor 2 surpassed upper limit set value, when perhaps the unusual mistake of wind speed was low, controller 1 sent alarm signal to the outside.Through above-mentioned closed-loop control, guarantee that heat abstractor effectively moves, prolong the useful life of electronic equipment 4.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection range of the utility model technical scheme according to the technical spirit of the utility model.
Claims (2)
1. a cabinet is used heat abstractor, comprises blower fan and controller, and controller control connects the power supply of blower fan, it is characterized in that: in the air channel of blower fan, air velocity transducer is set, air velocity transducer is given controller with electrical signal transfer.
2. use heat abstractor according to the described a kind of cabinet of claim 1, it is characterized in that: also comprise first or/and second temperature sensor, first or/and second temperature sensor electrically connects controller.
